Setup -- Zoning
Disable Zoning:
S
NO (default)
S
YES
If YES is selected, zoning is disabled and all dampers open. The
system will run un--zoned using the Zone 1 sensor.
Zone Offsets:
S
Zone Temperature Offsets (default = 0) Range --5

This option allows actual temperature offset for each zone,
allowing calibration (or deliberate miscalibration) of each sensor.
Humidifier interval is time only, not actual humidifier run time.
Airflow Limits:
Since bypass damper is prohibited in this system, this setting is
used to select the maximum allowable noise/airflow relationship
into each zone based on air noise and comfort requirements. For
setup guidelines, see Airflow Limits Checkout in the next section.
S
Low -- 100% of maximum assessed airflow
S
Med Low -- 138% of maximum assessed airflow
S
Medium -- 176% of maximum assessed airflow
S
Med High -- 214% of maximum assessed airflow
S
High -- 250% of maximum assessed airflow
S
No Limit -- equipment does not stage down
CFM associated for each limit is shown on the screen. Compare
this value with the equipment’s low stage CFM value to ensure that
equipment will run for each zone. Assessed airflow is determined
as described in DUCT ASSESSMENT.
Duct Assessment Time
1 p.m. (default), adjustable in 1 hour increments from 1 p.m. to 12
a.m. (24 hours). Select which hour of the day the duct assessment
will be performed.

DEFROST W/WATER:
S
Available settings: YES / NO (Default = YES)
S
Appears only if heat pump is available. If no, hot water will not
run during a defrost.
AIRFLOW -- Selects desired airflow during Hydronic Heating
S
Available range from OFF, 500 CFM(minimum) to 400
CFM/ton cooling maximum in 50 CFM increments.
S
Default is the cooling airflow. (350 CFM/ton)
S
OFF selection does not turn off airflow if heat pump is
defrosting.
BLOWER ON DELAY -- Time after hot water is requested that the
blower will turn on.
S
Available settings -- 0 to 240 seconds in 30 second increments
S
Default is 30
S
Does not appear if a heat pump is present since heat pump and
hot water run simultaneously.
BLOWER OFF DELAY-- Time after hot water request terminates
before the blower will turn off.
S
Available settings -- 0 to 240 seconds in 30 second increments

CLEAN INTERVAL: Never, 1 to 18 months. (Default = 90)
Enables a timer for the filter notification.
Interval at which the Clean Filter notification will turn on.
PRESSURE MONITOR: ENABLE/DISABLE -- enables the static
pressure calculation for media--type filters.
Humidifier Installed:
S
NO
S
YES
If YES, indicates to the system whether a humidifier is installed
and enables humidification functions.

months)
Interval at which the Change Humidify Pad notification will be
displayed.
HUMIDIFY WITH FAN (Heating Mode Only):
S
NO (default)
S
YES
If YES, the humidifier will turn on if there is a humidify demand
present. The fan will turn on to Low speed if the fan setting is
Auto.
